GATE.

Specification of Letters Patent.

Patented May 26, 1908.

Application filed May 17, 1907. Serial No. 374,282.

To all whom it may concern:

Be it known that I, GEORGE F. SEIsEn, a

citizen of the United States, and resident of- Port Royal, in the countyof Henry and State of Kentucky, have invented certain new and usefulImprovements in Gates, of which the following is a specification.

The object of my invention is to provide an automatically-operated gate;and it comprises a post to which the gate is hinged so that it may swingto and fro in each direction without changing the position of thehinges.

In the accompanying drawing, Figure 1 is a perspective view of a gateshowing the latter closed. Fig. 2 is a view showing the positions of thetriggers and locking devices. Fig. 3 is a side view of the gate. Fig. 4is a face view of the gate post showing the keeper for locking the gate.Fig. 5 is a view of the end of the gate next the gate post; and Fig. 6view of the gate post illustrating the side facing the gate.

In constructing my invention I provide a gate post 6 of suitable height,in the front face of which I provide a gain or cut-away portion 7, nearthe upper end. In this cutaway portion I place the upper end of a vertically-disposed rod 8, having at its upper end an outwardly-projectingbend 9, and, approximately, midway, a right-angled bend 10 which passesthrough and is pivoted in the post 6. The lower end of this rod has aweight 11.

On the front face of the post 6 is a vertically-disposed bar 12, pivotedapproximately one third of the distance from the bottom, to the post, asshown at 13. The lower end carries a crescent-toothed casting 14, and atthe upper end of the bar is a short verticallydisposed slot 15, in whichthe right-angled end 9 of the rod 8 operates. To the upper end of thispivoted bar I hinge the ends of two operating arms 16, which project outin opposite directions, and at right angles to the position of the gatewhen the latter is in a closed position. The ends of these arms have aseries of holes 17. In one of these holes is placed the upper end of thearm 18, which arm is an extension of the Wheel trigger 19. The end ofeach arm 16 has a right-angled bend 19. I

The gate 20 has a horizontal locking bar 21 secured in keepers 22, onthe sides of the stiles 23, 24.. The end of the locking bar on the stile24, is pivoted, as at 25, and adjacent the projecting end of thislocking bar, and

secured to the pivoted bar 12, on the gate post 6, is a pair ofprojections 26, between which the end of the locking bar rests. Theseprojections have inclined surfaces so that when .the pivoted bar movesin either direction one of these projections will engage with the end ofthe locking bar and thus raise the opposite end and free it from thelocking piece 27 on the locking post 28.

It will be seen that the stile 24 of the gate is pivoted at its upperand lower ends to the post 6 by brackets 6 so that the positions of thepivots are not changed, but the gate at all times swings normally on itsfixed hinge. A toothed segment 29 is attached to the lower end ofthestile 24, and this engages with the toothed crescent 14 on the lowerend of the pivoted bar 12.

In order to provide a means for locking the gate when it is open, and toenable the driver to close it or leave it open, a locking trigger 30 isprovided beyond each of the regular wheeI triggers 19. These lockingtriggers may be placed at any desired distance from the triggers 19. Oneend of a link 31 is hinged to an upwardly-projecting arm 32, and theother end of this link is attached to a hook-shaped catch 33, the hookof which is within operative range of the right-angled bend 19 on thearm 16, so that when the gate is swung in the direction of the movingvehicle the rightangled bend 19 will approach the hook 33 and engagetherewith, and thus hold the gate open until the wheel of the vehicledepresses the locking trigger 30 by whichmotion the hook is disengagedand the weight again closes the gate. A spring, not shown, attached tothe hook 33, holds it in its normal position. The driver has thus the 0tion to drive over the locking trigger and c ose the gate or avoid thelocking trigger and thus leave the gate open.

When the wheel of a vehicle strikes the trigger on either side of thepost, the arm 16 is moved upwardly, thus causing the lower end of thepivoted bar 12 to move toward the trigger thus depressed, and alsocauses the toothed crescent to swing the gate in the direction of themovement of the vehicle. At the same time one of the inclinedprojections 26 strikes the end of the locking bar 21, causing itsopposite end to rise and thus become disengaged from the locking piece27, per mitting the gate to swing. The weight 11, having its fulcrumabove the pivotal point of the bar 12, is raised a suflicient distanceto aflord a considerable pull, and, in swinging downwardly, carries thegate back to its normal position independently of the other trigger.

Vhat I claim as new, is:

1. In an automatically-operating gate, the combination of a post havingthereon a vertically-disposed pivoted bar, a pair of oppo-,sitely-projecting arms, and wheel triggers for opening the gateconnected therewith, a pair of wheel triggers for closing the gateconnected with a catch and within operative range of theoppositely-projecting arms, a toothed crescent at the lower end of thevertically disposed pivoted bar, means for swinging the bar into avertical position, a gate hinged to the post, having a toothed segmentat its lower end, engaging with the toothed crescent, and means forlocking the gate in its closed position.

2. In an automatically-operating gate, the combination of a post havingthereon a vertically-disposed pivoted bar, a pair of oppositely-disposedarms, at its upper end, and wheel triggers connected therewith, a rodhaving a weight connected with the upper end of said pivoted bar, a pairof projecting pieces with inclined surfaces above the pivotal point ofsaid bar, a gate hinged to the post having a toothed segment to engagewith the toothed crescent, a horizontal locking bar pivoted at one endto the gate and normally resting between the projecting pieces on'thepivoted bar, and a fixed post having a notched locking piece to engagethe locking 35 bar, as set forth.

Signed at Port Royal in the county of Henry and State of Kentucky this25 day of April A. D. 1907.
